TRANSMISSION METHOD WITHOUT THE NEED OF A MULTI-STAGE CHAIN SPROCKET OR GEAR, A CONTINUOUSLY VARIABLE AUTOMATIC TRANSMISSION, AND A CONTINUOUSLY VARIABLE AUTOMATIC TRANSMISSION MODULE

摘要

PURPOSE: A transmission method, a continuously variable automatic transmission, and a continuously variable automatic transmission module are provided to implement various combinations of gear ratios by controlling the radiuses of the variable contact rotor and the friction rotor.;CONSTITUTION: A continuously variable automatic transmission comprises a variable contact rotor(110), a friction rotor, and an elastic supporter(130). The variable contact rotor comprises a variable contact surface(111). The friction rotor can move in the direction to change the distance to the rotation center of the variable contact rotor and has a friction surface which contacts the variable contact surface of the variable contact rotor. The elastic supporter supports the friction rotor to move in the direction to change the distance to the rotation center of the variable contact rotor and elastically presses the friction surface formed along the periphery of the friction rotor against the variable contact surface.;COPYRIGHT KIPO 2011
